Sofrigam has always paid special attention to the
quality of its heat-sensitive packaging solutions and the materials used to
make them. The use of a thermal flowmeter is a further step forward in the
drive for continuous improvement in the company.

ISO9001, external audits: a well-established quality control process

We manufacture temperature-controlled packaging
solutions for the biggest names in the pharmaceutical industry. These big
names regularly audit our production site, which is another
reason for us to pay special attention to the quality of our packaging
solutions.

Quality control of polyurethane, Sofrigam production
site, Monchy-le-Preux, France

In fact, Sofrigam has implemented a quality control
process alongside its packaging solution manufacturing process to respond to
the requirements of ISO 9001 certification. Organizational methods, management
of non-conformities, followed by client satisfaction are some of the criteria taken
into account by the ISO 9001 certification which standardizes the quality
management system.

A wavelength meter to measure the
thermal quality of the components of insulated packaging solutions

Recently, the laboratory has acquired a wavelength meter, a
device for measuring the thermal resistance of an insulating material.

Although Sofrigam has a strong Quality team which
systematically checks the raw materials upon arrival and the end-products (insulated
boxes and packaging solutions, etc.), Sofrigam is going even further in its
quality control process with the wavelength meter. This device, also known as a
thermal flowmeter, measures the thermal resistance of an insulating material.

Thibault Pech, a R&D engineer within the Ater Métrologie laboratory, explains
how it works:

“The wavelength meter consists of two plates which sandwich
the insulating material. Each plate is set at a different
temperature, of between -10°C and +90°C inclusive. If you want to know the
thermal conductivity of a material at +5°C for example, you set one plate at +10°C
and the other at 0°C. Once the balance is reached, the thermal flowmeter will
measure the thermal flow exchanged between both plates and calculate the
thermal resistance of the material.”

It represents a tremendous tool for Sofrigam which
uses it to control the quality of the components of its packaging solutions.

In
fact, the wavelength meter allows Sofrigam to not only verify the thermal
properties of the polyurethane insulating material, the external cardboard of
its insulated boxes or even the fabric coverings used in its cooling bags,
but also verify the evolution of the thermal conductivity of these materials
over time.

And this allows us to offer our clients even more efficient
insulated packaging solutions!
